  • Patent number: 10597020
    Abstract: A hybrid electric powertrain includes an electric machine delivering torque to an engine in an engine start event having initial cranking and transition phases. In response to a request for an engine start event, a controller commands delivery of the motor torque to the crankshaft. In the initial cranking phase the controller regulates crankshaft acceleration from zero speed up to a target cranking speed in a closed-loop manner via a predetermined fixed profile. In the transition phase, the crankshaft accelerates from the target cranking speed to a target idle speed using a feed-forward torque value blended, using a calibration table, from a predetermined engine drag torque to a reported engine torque. In the transition phase the controller periodically adjusts a speed trajectory of the crankshaft, with the magnitude and frequency of adjustment based on combustion of the engine and calibration of the feed-forward torque.

  • Patent number: 10586446
    Abstract: Disclosed is an identification system to improve safety on roads and allow for the driver or for the vehicle itself, if it is autonomous or semi-autonomous, to have readable and useful information about road signs, roadways, and adjacent roadway information. The disclosed identification system comprises a marker with marker communication information that can be read by a vehicle information system to provide information to the vehicle. Information that the marker communication information may convey would allow the vehicle information system to detect or recognize, or both detect and recognize critical road sign, roadway information, and adjacent roadway information. Then, the vehicle information system could respond to the information received from the marker communication information.

  • Patent number: 10530311
    Abstract: Aspects disclosed in the detailed description include an envelope tracking (ET) amplifier circuit. The ET amplifier circuit includes ET tracker circuitry configured to provide an ET modulated voltage, which tracks an ET modulated target voltage, to an amplifier circuit(s) for amplifying a radio frequency (RF) signal. The ET amplifier circuit also includes fast switcher circuitry that is activated to provide an alternate current (AC) current to the amplifier circuit(s) when the RF signal includes a higher number of resource blocks (RBs). However, the fast switcher circuitry and its associated control circuitry may incur a processing delay that can cause the fast switcher circuitry to lag behind the ET modulated target voltage. As such, the ET amplifier circuit further includes timing adjustment circuitry to help compensate for the processing delay, thus helping to maintain efficiency of the ET tracker circuitry for improved performance of the ET amplifier circuit.

  • Patent number: 10097145
    Abstract: A multi-mode power management circuit is provided. The multi-mode power management circuit includes a second generation (2G) amplifier circuit(s) configured to amplify a 2G radio frequency (RF) signal for transmission in a 2G RF band(s). The multi-mode power management circuit includes a pair of tracker circuitries coupled to the 2G amplifier circuit. Each tracker circuitry includes a charge pump circuitry configured to generate a voltage and a current. When the 2G amplifier circuit amplifies the 2G RF signal for transmission in the 2G RF band(s), both charge pump circuitries are controlled to provide two currents to the 2G amplifier circuit. As a result, the 2G amplifier circuit is able to amplify the 2G RF signal to a higher power corresponding to a sum of the two currents for transmission in the 2G RF band(s).
